Gap with GPIO pin
If you want to write your own code I suggest you avoid the magic numbers (which are error prone and almost impossible for anyone to read).
I have listed a fragment of my code which may help.

PIR sensor using 3.3v?
You can create a 5V rail using a breadboard. If not that, then you can use a 9V battery and pass it through a voltage regulator like lm7805 to get the desired voltage. To create a rail, connect 5V to ...

Checking angle of servo motor with a Raspberry Pi 3B+
RC models servos behaves as an open loop (no feedback) from the controller point of view, you set the desired angle by modulating the PWM signal (this could be easily done trough a library) and the ...

DC Motor not responding to GPIO Motor
I found out that what needed to be done was to convert Broadcom numbers to GPIO numbers on the Raspberry Pi, as hinted in user joan's comment.
After following this mapping: https://www.raspberrypi-spy....

DC Motor not responding to GPIO Motor
You have 3-pin controller board so you should initialize your Motor class with enable pin, e.g. for Motor1:
motor1 = Motor(forward=15, backward=13, enable=11)
Since you got the "Motorshield"...

Motor Controller Board Uncertainty for Raspberry Pi
I suggest you look at motor driver boards based on one of the following chips
L298N
L29D
L9110S
Each chip allows you to control two motors, forward, backwards, and control speed (using PWM on the ...

Checking angle of servo motor with a Raspberry Pi 3B+
You can try and correlate this yourself, as even different servos of the same make and model (nb. I've mostly only used cheap little things like generic SG90s) will have clear differences this way, ...

Checking angle of servo motor with a Raspberry Pi 3B+
Generally servos have no method of reporting their position. You command it to an angle and have to assume it went to that angle.
I assume gpiozero just returns the angle you last requested. Given ...

RPi 4: What happens when reverse voltage is supplied to the GPIO header?
The expansion header GPIO must not be exposed to a voltage outside the range 0V to 3.3V.
The expansion header voltage rail pins have no protection. If you reverse the voltage on the 3V3 or 5V pins ...

How to run Hyperpixel 4.0 on I2C-0 (GPIO's 44&45)?
The I2C pins on the touch controller are wired to the software I2C pins (GPIO 10 & 11) on the display. Nothing you can do in software can move these PCB traces. The i2c_gpio driver that is loaded ...

how to connect to GPIO connectors if they are already occupied
To connect something else to the GPIOs you have the following options:
Use stackable pin header (or the 90 degree one) between the boards you show and solder your button to it.
Use PCB with stackable ...

Can't turn on ACT LED on baremetal Pi3
The shift should be 15 bits not 16, your 1 as the first bit would already be in bit 0 before the shift and needs to be in bit 15, ie the 16th bit.
Your code is placing a 1 in the 17th bit so is in the ...
